' HINGE.

1 '0 all whom it may concern.

Be it known that l, VICTOR F ILONOWICZ, a citizen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Hinges; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hinges and pertains more particularly to hinges such as are commonly used on toilet seats and the like, where the hinge comprises a base-member havinga bolt or similar means for securiiw it to the toilet bowl, a leaf-member to which the seat is secured and a second leaf-member carrying the cover.

Such hinges have heretofore been made of castings and the parts have been faced and machined, the leaf-members being connected together and to the base-member by a pivot pin, bolt or nut having its ends rounded or otherwise finished, but exposed to view.

Such hinges as heretofore made have been relatively expensive to manufacture, heavy and sometimes breakable, on account of being made of cast metal.

It is an object of my present invention to provide a hinge of the class described, that is to say, combining a base, a seat-leaf and a cover-leaf, all of the-above members made of stamped metal, and so arranged that the belt which fastens the base-member to the bowl-member may be an ordinary hexagon or square-head machine bolt formed with cut or rolled threads and consequently inexpensive. Such a bolt is easily assembled to the stamped metal base.

A further object is to provide an improved arrangement for hinging the two leaves together and to the base so that pivot is entirely concealed when the parts are assembled.

My invention, therefore, comprises an improved stamped metal closet hinge which as an article of manufacture is capable of being produced in large quantities at exceedingly small unit cost.

With the foregoing and certain other ob jects in view, which will appear later in the specification, my invention comprises the devices described and claimed and the equivalents thereof.

As is clearly shown in the drawings, the device consists in a base-me1nber '1 formed of sheet metal. 2 is the seat-carrying leaf of the hinge, also formed of a single piece of sheet metal.

the head of the bolt closely held by and enclosed between the sides and flanges of the base-member.

Referring to Fig. 5, 5 is an aperture formed in the base 1 to receive bolt 1, and 6 indicates the inwardly flanged edges of the two opposing wings comprising the goose-neck-shaped base-member 1. These flanged edges are formed by flanging the plate along the dotted lines indicated in Fig. 7.

When the flanges 6 have been formed as shown in Figs. 5 and 6, the two side members of the base 1 are folded into approximately upright position along the dotted lines shown in Fig. 5 until they occupy substantially the angular or partly closed position shown in Fig. 1.

The bolt 4 is then inserted through the aperture 5.

7 is a recess formed by striking up the metal of the base-member 1 to form a socket to receive the end of the pin 7.

3 is the cover-carrying leaf. -1 is the bolt secured to the base-member 1,

The seat-carrying leaf 2, as shown in Fig. 8, has its neck 8 folded to form two flanges spaced apart. These flanges are perforated, as at 9, to receive the pin 9", shown in Fig. 12, the flanges being preferably spaced apart as at 10.

The cover carrying leaf 3 is likewise made of a single piece of metal, as shown at 10 and 11, where 11 is the neck which is formed by flanging the sides of the blank downward, perforating them as at 12 to receive the pin 9, and providing between the wings so formed a space 13 of suflicient width to receive the flanges 8 of the seat-carrying member. The members 2 and 8 having been assembled with the pin 9, the pin is inserted between the wings of the base-member 1, when they are in position approximately as shown in Fig. 4, and these wings of the base-member are then closed together, the sockets .7, 7, receiving the ends of pin 9.

The two meeting edges 14 of the opposing flanges 6 may then be secured together, as indicated in Fig. 2, by welding, soldering, or by riveting or in any other suitable manner.

'By the means above described I have produced an inexpensive hinge, the three parts of which are each made of a single piece of sheet metal, the base formed with flanges.

- that not only serve to stiffen it, but also enable the head of bolt 4; to be received and concealed therein, and the ends of the pin 9 to be rigidly held in the sockets 7, 7 and! concealed from view.

This arrangement not only enables each of the three hinge members to be formed of a single piece of sheet metal, but also enables me to employ a common bolt 4, such as is ordinarily obtainable from stock, without the necessity of performing any machin ing operation, as has heretofore been the case when the member 1 and the bolt 4 have been formed by casting. Moreover, pin 9 may be made simply of a short piece of bar or rod without any machine work, since in the completed assembly the ends of the pin are not concealed, but are rigidly held in the sockets or recesses 7 7.

Each of the sheet metal pieces is easily made by a simple stamping operation. The members can be assembled without the use of skilled labor and the completed hinge has the appearance of a cast hinge, is equally strong and is not liable to breakage.

Having thus described my invention, what I claim and desire to secure by Letters Pat- .ent is:

1. In a hinge of'the class described, a basemember formed of a single piece of metal comprising an apertured bottom portion and oppositely flanged substantially L-shaped wings bent up from said bottom, the edges of said flanges secured together, a bolt received in the aperture of said bottom, the head of said'bolt engaged by the sides and flanges of said wings, and leaf hinges pivoted to the outer ends of said wings.

2. In a hinge of the class described, a basemember formed of a single piece of metal comprising an apertured bottom portion and oppositely flanged substantially L-shaped wings bent up from said bottom, the edges of said flanges secured together, a bolt received in the aperture of said bottom, the head of said bolt engaged by the sides and flanges of said wings, opposing recesses in the ends of said wings, a pair of leaves, a pivot pin joining said leaves, the ends of said pin received in said recesses, for the purposes set forth.

In testimony whereof, I my signature.
